Introducing the next generation of folding covers ? the UnderCover Flex folding cover. Flex combines the best of both worlds, the security of a hard locking cover and convenience of a soft roll up cover. Constructed from the best materials available, Flex will withstand the abuse Mother Nature throws at it and keep coming back for more. Low Profile ? Ultra-low profile design rests inside the bed rails allowing for a very sleek look. Full Access ? Built in prop rods secure the cover allowing your truck to be driven with the cover fully open. Easy Removal ? Entire cover can be removed in seconds with no tools needed. Secure Design ? Plastic buckles and straps are included to secure the panels in the partially open position. FRP Composite Panels ? Lighter, stronger and higher dent resistance than aluminum. Weather Resistant ? Rubber seals and drain tubes channel water away from and out of the bed. No Drill Install ? Clamp-on no drill installation on most applications. No other folding cover can match the Flex for versatility, security and function. Covered or uncovered, always and option with UnderCover.
